Jing - UK-India Bi-lateral Workshop on Sustainable Energy and Smart Grid
UK-India Bi-lateral Workshop on Sustainable Energy and Smart Grid.
Sustainable energy and Smart Grid technology are now very important to ensure national energy security. New advances in electric vehicles, embedded generation and storage, power electronics, wireless sensors, and communication technologies bring new challenges and innovation to the energy industry. The multidisciplinary nature and the impact of these technologies are important to investigate. The introduction of free market environments and CO2 targets raises further complex issues including demand side response and pricing. Hence, the realisation of these technologies will require a major effort from all stakeholders.
This workshop aims to bring researchers and academics in the field together to discuss current work carried out in related research groups in UK and India, key future challenges that still need addressing, and possible opportunities of collaboration. In particular, the workshop will seek to identify needs in India and UK that would benefit from bilateral collaborations, and further strengthen UK-India ties. Participants will be able to give presentations of their work, and discuss areas of collaborations.

Those rising edges contain high-frequency energy from harmonics of the PWM signal's frequency. Because a motor presents an inductive load to the inverter circuits, its inductance filters much of the high-frequency energy. The high frequencies do little to rotate the motor, but the energy in those frequencies must go somewhere, and the high-frequency energy dissipates as heat.
